Wiki acute appendicitis without peritonitis, unspecified code?

[jodielonkoski]

Curious if anyone has any insight on why acute appendicitis without peritonitis would be an unspecified code, K35.80? We have an insurance carrier who denies claims with 'unspecified' in the primary or secondary code description. We see a lot of acute appendicitis. If the appendix has not yet ruptured, and there is no peritonitis, the book directs to K35.80 which is an unspecified code. Why is this unspecified? There is no further specification...there is no peritonitis. I have not been able to find any justification on why this should or would be an unspecified code, but the description lists 'acute appendicitis without (localized) (generalized) peritonitis'.... what about that is unspecified?? help!

ICD-10 code and usage

• K35.80: Unspecified acute appendicitis.
• Rationale: The code description explicitly includes "Acute appendicitis without (localized) (generalized) peritonitis".
• Why it might be used: This code is for cases where the appendicitis is acute but has not progressed to the point of causing peritonitis, perforation, or gangrene, and the provider's notes do not provide more specific details.

How to avoid denials

• Use the most specific code available: If the documentation includes more details like perforation or localized peritonitis, use the corresponding specific code, such as K35.30 (Acute appendicitis with localized peritonitis, without perforation or gangrene) or K35.32 (Acute appendicitis with perforation, localized peritonitis, and gangrene).
• Ensure complete documentation: Vague notes can lead to claim denials. To ensure the use of K35.80 is justified, the provider's documentation should clearly state that there is no peritonitis, perforation, or gangrene.
• Avoid using unspecified codes unnecessarily: Using an unspecified code when a more specific one is available is a common reason for denial.

Appreciate the reply but my question is more WHY acute appendicitis without perforation or peritonitis would be 'unspecified', when there is nothing further TO specify. We have an insurance carrier denying all claims where an unspecified code is primary or secondary, regardless of that being justified or not. They are requiring our providers to supply a more specified diagnosis. With acute appendicitis without perforation or peritonitis this is....not possible. Obviously this is a issue with this insurance carrier, but it still begs the question to me of WHY this would be unspecified. 'Acute appendicitis' on its own, sure, but when they do specify its early acute and there is no perforation or peritonitis....there is nothing further to specify.

I agree with you. The Insurance shoud understand this unless the description of the ICD code is revised by the CMS. Please make the efforts to comprehend the same to the respective SPOC of the respective insurance carrier. Otherwise, this will be a never ending story of denials. Hope this helps!
